Scientists may know about vaccine by December: Dr. Anthony Fauci

U.S.’ leading infectious disease expert Dr. Anthony Fauci said that by the end of this year, government scientists should know whether they have a safe and effective vaccine for COVID-19.

Dr. Fauci said that people who recover from the virus develop antibodies against it, which gives him confidence a vaccine that triggers the immune system will work.

He added that several kinds of vaccines are in final-stage testing in the US. A single-dose candidate is the most recent trial, which requires thousands of volunteers. – AP
